IMPROVEMENT IN COTTON-cms.

Specication forming part of Letters Patent No. 58,187, dated September 18, 1866.

To all whom it may concern:

Be it known that we, FREDERICK TABoR AcKLAND, HENRY GEORGE MITCHELL, and MUSTAPHA MUsTAPHA, of Zagazig, Egypt, have invented certain new and useful Improvements in Cotton-Gins; and We hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings'.

The said invention relates to a peculiar construction and arrangement of selfacting mechanism for feeding cotton-gins, whereby a more regular and certain feed is obtained than by the mechanism heretofore adopted for that purpose.

According to this invention it is proposed to apply to the ordinary McCarthy gin, orto other gins of a like character, a self-acting feeder, which reci procates to and fro in a rectilinearor straight course, and imparts a direct push to the cotton, so as to move it forward by a positive motion to the ginning-roller and doctor as fast as it is fed into the feedinghopper.

This feeder consists of a bar of wood, metal, wire-work, or other suitable material, of a length equal to that of the ginnin g-roller, which bar is situate inside the hopper parallel to the axis of the said roller. This feeding-bar reciprocates toward and from the ginning-rol'ler andJits doctor along the grid upon which it rests, its motion being derived directly from cranks or eccentrics' on a shaft contained within the back portion of the hopper. As fast as the cotton is supplied to the hopper it falls at each back stroke of the feeder in front of the forward edge or face thereof, so that when the feeder returns toward the ginning-roller and doctor it pushes that portion`of the cotton immediately in front of it directly against the said roller and doctor and then recedes for a fresh supply, which is again pushed forward as before, and so on and in order that the said invention maybe fully understood we shall now proceed more particularly to describe the same, and for that purpose we shall refer to the gures on the sheet of drawin gs hereunto annexed, the same letters of reference indicating corresponding parts in both of the figures.

Figure 1 of the drawings represents a side elevation of an improved McCarthy gin provided with the above-described self-acting feeder; and Fig. 2 is a vertical section of the upper part of the gin on a larger scale, showing more clearly the construction and operation of the feeder.

A represents one of the two side standards of the gin.- B is the main driving-shaft, and C is the shaft of the ordinary leather-covered ginning-roller l). E is the doctor or fixed knife. F is the vibratingbeater-plate, attached to the radius-rod G, which works on a Xed center atl- T, and derives its motion from a crank on the main shaft and a connecting-rod,

I. K is a feeding-hopper, and L the grating or grid, all which partsare common to gins of this class, and form no part of the present invention, which has reference solely to the feed- Vof the hopper.

l? represents one of two connecting-rods, which connect the feeding-bar M with its actuating-cranks on the crankshaft NQ A pulley, Q, is'keyed onto one end of the crank-shaft N, and a corresponding pulley of equal diameter, R, is keyed onto one end of the main driving-shaft, motion being transmitted from suchpulley to the crank-shaft by the band S.

The cottonto be fed into the machine is laid upon the table T, and is th ence pushed by hand down the inclined side of the hopper, to the lower edgevofl which a ap, U, of leather or other suitable material is secured, for the purpose of preventing any of the cotton from entering behind the feeder. As the-feeder advances its front edge or face, me., pushes the cot-ton before it against the'ginning-roller'and doctor, which seize it and remove the seeds therefrom in the well-known manner. i

Having now described and particularly ascertained the nature of the said invention and in what manner the same is or may be used or carried into effect, We would observe in con- Itextends I 2 asas? In testimony whereof we have signed our naines to this speoiication in the presence of two subscribing witnesses.
